Overview

Bilstein B6 4600 shock absorber 24-131599 is a direct-fit upgrade for stock-height light trucks and SUVs. It uses a monotube design and a velocity-sensitive digressive piston to deliver consistent damping as road conditions change.

Fits 2003-2006 Ford Expedition, rear. This application-specific shock is tuned for the vehicle platform to improve ride quality, handling, and comfort without changing the stock-height setup.

Key Features

  • Monotube internal design for consistent fade-free performance.
  • Velocity-sensitive digressive piston reacts to changing road inputs.
  • Non-adjustable damping for straightforward replacement.
  • Yellow painted finish and stem upper mount with eye lower mount.
  • B6 4600 series shock absorber, part number 24-131599.

Detailed Description

The Bilstein B6 4600 24-131599 is built as a direct-fit shock absorber upgrade for stock-height applications. Its monotube construction helps maintain stable damping performance, while the digressive piston is tuned to respond to varying road conditions for controlled ride behavior. For Ford Expedition owners, this rear shock is matched to the specific application to support improved comfort and handling compared with a worn OE unit.

Bilstein B6 4600 is the product line for drivers who want an OE-style replacement with upgraded damping characteristics. The series is engineered for light trucks and SUVs at stock ride height, making it a practical choice when restoring suspension response on a Ford Expedition. Part number 24-131599 is also referenced by 24-186131 for the same application.

What It Helps Address

  • Excessive bouncing after bumps or dips.
  • Reduced control from worn shock absorbers.
  • Harsh or inconsistent ride quality.
  • Loose handling feel during normal driving.
  • Loss of damping consistency as components age.

Installation Notes

Verify rear fitment, stock ride height, and mount style before installation. This shock uses a stem upper mount and an eye lower mount with a 20.3 mm lower eye. Confirm the existing suspension configuration on the Ford Expedition before replacing the original unit.

Quality Assurance

Bilstein designs the B6 4600 series as an application-specific monotube shock absorber with tuned damping characteristics for the listed vehicle fitment. Part number 24-131599 reflects the same rear application coverage as the listed cross-reference.
